2008-06-03mac80211: fix deadlock in sta->lockTomas Winkler
This patch fixes a deadlock of sta->lock use, occurring while changing tx aggregation states, as dev_queue_xmit end up in new function test_and_clear_sta_flags that uses that lock thus leading to deadlock Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Ron Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: John W.

2008-06-03rndis_wlan: use ARRAY_SIZE instead of sizeof when adding 11g ratesScott Ashcroft
While figuring out the TKIP problem I found a bug in the code which adds the 11g rates. It's using sizeof instead of ARRAY_SIZE to terminate the for loop. This makes it fall off the end of the rates array start into the frequency array instead. Running "iwlist rate" should show the problem as there will always be 32 rates with the last few being bogus. The following patch will fix it. Signed-off-by: Scott Ashcroft <scott.ashcroft@talk21.com> Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

2008-06-03libertas: before sleeping, check for a command resultHolger Schurig
If we don't check for a command response early, but rather sleep, then we might sleep despite an already-received command response. This will lead to a command-timeout.

2008-06-03mac80211: clean up skb reallocation codeJohannes Berg
This cleans up the skb reallocation code to avoid problems with skb->truesize, not resize an skb twice for a single output path because we didn't expand it enough during the first copy and also removes the code to further expand it during crypto operations which will no longer be necessary.

2008-05-21mac80211: remove channel use statisticsJohannes Berg
The useless channel use statistics are quite a lot of code, currently use integer divisions in the packet fast path, are rather inaccurate since they do not account for retries and finally nobody even cares. Hence, remove them completely. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21b43: Add firmware markers supportMichael Buesch
This adds support for firmware markers. With firmware markers it's easily possible to check whether the firmware runs some codepath or not. The driver will throw a message when the firmware executes a MARKER(x). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21b43: Add panic reason code that doesn't trigger restartMichael Buesch
Add a firmware panic reason code that doesn't trigger a restart. This is useful for firmware debugging and avoiding endless restart loops.

2008-05-21mac80211: use multi-queue master netdeviceJohannes Berg
This patch updates mac80211 and drivers to be multi-queue aware and use that instead of the internal queue mapping. Also does a number of cleanups in various pieces of the code that fall out and reduces internal mac80211 state size. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21mac80211: dont allow fragmentation and requeuing on A-MPDU queuesJohannes Berg
There really is no reason for a driver to reject a frame on an A-MPDU queue when it can stop that queue for any period of time and is given frames one by one. Hence, disallow it with a big warning and reduce mac80211-internal state. Also add a warning when we try to fragment a frame destined for an A-MPDU queue and drop it, the actual bug needs to be fixed elsewhere but I'm not exactly sure how to yet.

2008-05-21zd1211rw: Use DMA-aware buffer for usb transferAtsushi Nemoto
The zd1211rw driver uses unaligned stack buffer for USB control message. But it might cause stack corruption on non-coherent platform, such as MIPS. Use DMA-aware buffers for USB transfer. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21mac80211: move TX info into skb->cbJohannes Berg
This patch converts mac80211 and all drivers to have transmit information and status in skb->cb rather than allocating extra memory for it and copying all the data around. To make it fit, a union is used where only data that is necessary for all steps is kept outside of the union. A number of fixes were done by Ivo, as well as the rt2x00 part of this patch.

2008-05-21mac80211: reorder some transmit handlersJohannes Berg
The next patch will require that transmit handlers that are after fragmentation are aware of the fact that the control info is also fragmented. To make that easier, this patch moves a number of transmit handlers before fragmentation. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21mac80211: use rate index in TX controlJohannes Berg
This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers. This mostly serves to reduce the TX control structure size to make it fit into skb->cb so that the fragmentation code can put it there and we can think about passing it to drivers that way in the future. The rt2x00 driver update was done by Ivo, thanks. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-21mac80211: let drivers wake but not start queuesJohannes Berg
Having drivers start queues is just confusing, their ->start() callback can block and do whatever is necessary, so let mac80211 start queues and have drivers wake queues when necessary (to get packets flowing again right away.)

Commit 55c308c1315bc7267dbb88011c208fd743cdce31 ("mac80211: QoS related cleanups") introduced another bug, the queue handling functions that operate on all queues now only operated on the first queues, not the A-MPDU queues as expected.
